Airtel — airtel post paid fraudulent services

Address:

560003

I am a resident of malleswaram, yellappa garden, bangalore & have been an airtel post paid consumer since april 2018, ported from vodafone, after coaxing from airtel promotions team that the network is great now!!.
From day one, i have faced daily problems of voice breaking & call drops & only 2g ('e') connectivity most of the time & occasional 'h'.
In june airtel customer care acknowledged my concern & sent a technician to check the connectivity & was confirmed that there a connectivity issue in the spot where i stay.
The internet speed is such that even i keep the data 'on' 24 hours i cannot consume 1 or 2gb in full month. The 2gb/day service offer & the corresponding charges is a complete hogwash & misleading on the part of airtel & they are charging/billing me fully & promptly every month for the completely inadequate services they offer to me. I have been paying bills every time with great irritation & feeling letdown.
My question is how fair is it on the part of airtel to bill me for the services they bill for but never met in full. I consider it as a fraud & need to be addressed at the highest authority possible.
